I think the thing I like most about Saxxon's work, regardless of the type of expansion involved, is the sheer glee and gusto poured into it. Plus the way he frames his sequences in genuinely entertaining stories.
Speaking of which, here's a BE sequence he did as a commission. It doesn't appear in his main gallery, but he linked to it in his journal so I assume it's alright:
